I've been using the Aguilar GS212, which I totally love. I have also tried the Epifani T212, which didn't sound good for me at all. It sounded much better for the guy trying to sell it to me. He had some 1600-watt power amp, whereas I "only" have a Thunderfunk. Still, the Aguilar has sounded good with almost any combination of amp & bass. The Aguilar 212 fills the stage and the room. No PA needed. 10s, I found too focused. The sound level from spot to spot in the room was very uneven with 10s. The Aguilar 212 weighs <70 lbs and costs <$700 new, making it a very practical all-in-one solution. To be even more practical, I am now switching to a pair of Aguilar GS 112s. I can take only one for most non-loud situations, and they weigh 40 lb. each. (And do a surprisingly close to complete job, sonically. Two together are a definite improvement, but one ain't half bad.)
